[PATCH AUTOSEL 5.14 16/99] clk: renesas: rzg2l: Fix return value and unused assignment

[Sasha Levin <sashal@kernel.org>]

From: Yang Li <yang.lee@linux.alibaba.com>

[ Upstream commit 97c29755598f98c6c91f68f12bdd3f517e457890 ]

Currently the function returns NULL on error, so exact error code is
lost.  This patch changes return convention of the function to use
ERR_PTR() on error instead.
